Thermistors in Single Supply Temperature Sensing Circuits

the thermistor sensor can be used to time delay a reaction to changes in conditions in a circuit. If a thermistor is overdriven, the thermal mass time constant of the sensor eventually causes the thermistor to overheat, reducing its resistance. Resistance-Versus-Temperature Mode By far, applications using the first mode, resistance-ver- sus-temperature, NTC Thermistor configurations, …

Thermistor | Analog Devices

Thermistors are a type of semiconductor, meaning they have greater resistance than conducting materials, but lower resistance than insulating materials. The relationship between a thermistor’s temperature and its resistance is highly dependent upon the materials from which it’s made and is referred to as the temperature coefficient. It is composed of materials with known resistance and ...

How to Build Simple Thermistor Circuits

How this circuit works is we form a voltage divider circuit between the 100KΩ thermistor and a 50KΩ fixed resistor. At room temperature, the thermistor offers its nominal value of near 100KΩ. Voltage divides in a voltage divider circuit according to the resistance of each of the components, based on Ohm's law, V= IR. Thus, the greater the resistance of a component, the more voltage that ...

Make an Arduino Temperature Sensor (Thermistor Tutorial)

Let’s build a basic thermistor circuit to see how it works, so you can apply it to other projects later. Since the thermistor is a variable resistor, we’ll need to measure the resistance before we can calculate the temperature. However, the Arduino can’t measure resistance directly, it can only measure voltage. The Arduino will measure the voltage at a point between the thermistor and a ...
